Is moved to a discharge position where the work 11 is discharged into the work storage box 7 when the work is lowered. ".

In the conventional work storage device shown in FIG. 11, the work 11 can be stored in the work storage box 7 so as not to damage the work. However, the work storage box 7 is not replaced. Therefore, it is difficult to say that the overall efficiency has been improved. That is,
For example, parts such as bolts and nuts are manufactured at a high speed and in large quantities by a parts manufacturing machine as described above. When the parts are packed into a box, the work storage box 7 as shown in FIG. And the next empty box must be prepared. The provision or replacement of this empty box is a substantial problem in practice.

[0005] Then, it seems good to make the work storage box 7 large, but if a large number of parts are put in a large box, the whole becomes very heavy and only the transportation becomes difficult. However, there is a problem that the lower part is easily scratched this time due to the weight of the upper part and the like. For this reason, the work storage box 7 cannot be made so large, so that the work storage box 7 needs to be quickly replaced and replaced frequently.

The work storage box 7 of this type, that is, the parts storage box, is made of synthetic resin with a certain standardization. This is because stacking can be performed with a fixed amount of storage and provided at low cost. On the other hand, parts such as bolts immediately after completion remain hot due to metal machining, and if this is packed immediately after completion, the heat will heat the parts storage box. become. The heat from these parts may cause the plastic storage box to soften and deform, and as the storage box is used over and over again, the deformation will gradually increase. .

To summarize the above, there is the following demand for an apparatus for packing parts such as bolts into a box. The ability to automatically replace parts storage boxes without requiring human intervention. No other need for an empty box location. In addition to the above, by making the storage work space small, the whole can be made compact. Devise the storage space to prevent parts from being damaged. The parts storage box is deformed and these are in close contact with each other
Even in the fitted state, it is possible to reliably take out one by one, so that the automation of the packing operation can be reliably performed.

The inventor of the present invention has conducted various studies on this kind of parts boxing apparatus to meet the above-mentioned requirements, and as a result, completed the present invention.

By 3a, the movable table 41 of the empty box holding device 40 moves up and down while correcting the inclined state of each parts storage box 60. Needless to say, when the empty box holding device 40 is moved up and down with respect to the parts storage box 60, the holding rods 44a of the holding cylinders 44 are retracted.

Now, as shown in FIG. 1, the empty box holding device 40 holds only the lowermost parts storage box 60 with the support base 20.
In the case of lifting the remaining empty box holding device 40, the entire empty box holding device 40 descends to the position shown by the lower virtual line in FIG. 1, and for example, as shown in FIG.
By actuating 4, each holding rod 44a is made to protrude. Each protruding holding rod 44a is
Upper edge flange 61 of parts storage box 60 located in the second stage
When the entire empty box holding device 40 is moved upward as it is, the other parts storage boxes 60 are left on the support base 20 while the other parts storage boxes 60 are left as shown in FIG. It will be lifted as shown in.

As described above, since the machine frame 10 has a work space necessary for opening and closing the guide gutter 33 and inserting parts P, when the empty box holding device 40 is raised, it is held by this. The lower part storage box 60 and the support base 2
A work space having a size as shown in FIG. 1 is sequentially formed between the first and upper parts storage boxes 60 on the top of FIG. Therefore, the guide gutter 33 is opened and the parts P are put into the first-stage parts storage box 60 from the tip. When the input of the parts P into the first-stage parts storage box 60 is completed, the second-stage parts storage box 60 is stacked on the first-stage parts storage box 60. Done.

First, the fact that the inside of the first parts storage box 60 is full of parts P is determined by, for example, counting by a counting device (not shown) on the parts manufacturing machine side, parts P by an area sensor provided on the guide gutter device 30 side. Or the number of passes through the parts storage box 60 or an optical sensor for detecting the full state of the parts storage box 60. If it is detected that the inside of the parts storage box 60 is full,
The guide gutter 33 is closed by operating the opening / closing cylinder 34 on the guide gutter device 30 side, and the drive gutter 32 is operated to move the entire guide gutter device 30 into one parts storage box 60.
Up by the height of Then, the entire empty box holding device 40 is lowered, and on the full parts storage box 60,
As shown in FIG. 8, the upper parts storage box 60 is placed.

The second part storage box 6 for the upper part of the first step
When the mounting of the “0” is completed, each holding cylinder 44 is operated to retract the holding rod 44 a, and the entire empty box holding device 40 is raised by the height of one parts storage box 60. Thereafter, the respective holding cylinders 44 are operated again to project the holding rods 44a, so that the respective holding rods 44a are engaged with the lower side of the upper edge flange 61 of the third-stage parts storage box 60. Then, when the entire empty box holding device 40 is raised again, the remaining empty boxes are placed in a state where the full parts storage box 60 and the empty parts storage box 60 thereon are placed on the support base 20. The parts storage box 60 is lifted up again.

By performing the above, the support 2
The work space shown in FIG. 1 is always located between the uppermost empty box on the top of FIG. 0 and the lowermost part of the parts storage box 60 lifted by the empty box holding device 40.
In this work space, the guide gutter 33 on the guide gutter device 30 side can be opened. In other words, the working space shown in FIG. 1 rises by the height of the parts storage box 60 every time an empty box is prepared, and the size is always kept constant. There is no change in the space around the parts boxing device 100.

In other words, according to the parts boxing apparatus 100, the space for the large number of parts storage boxes 60 and the working space are already prepared inside, so that the surroundings are empty or full. No space is required for stacking the parts storage boxes 60, and if the parts boxing device 100 is attached to a parts manufacturing machine, it is difficult to secure extra working space around the parts manufacturing machine. It is completely unnecessary.

Accordingly, the parts boxing apparatus 100 is very compact as a whole, and can handle any type of parts manufacturing machine (not shown). The inside can be refreshed. Of course, each part P sent out from the parts manufacturing machine receives the
Of each part storage box 6
Since it is subdivided into zero, it is not damaged. The parts boxing apparatus 100 can automatically pack each part P into a large number of parts storage boxes 60.

Further, in order to solve the above-mentioned problem, the means adopted in the invention according to claim 2 is that the parts box packing apparatus 100 according to claim 1 is configured such that “the guide gutter 33 of the guide gutter device 30 In such a manner that the parts P are vertically moved in a plurality of stages in the work space so that the parts P are packed in a substantially flat state in the parts storage box 60 ”.

That is, in the parts boxing apparatus 100 according to the second aspect, the guide gutter 33 constituting the guide gutter apparatus 30 is moved within the predetermined working space once formed by the upper and lower two parts storage boxes 60. In this case, as shown in FIG.
That is, in the parts packing apparatus 100, the parts P are packed into the parts storage box 60 at a low position indicated by a dotted line in FIG. The next box packing is performed at a high position shown by a solid line in the middle).

This is particularly the case for the parts storage box 6.
If 0 is a large one, and if the guide gutter 33 seems to be able to insert the parts P only at a certain position, as shown in FIG. This is because it will be heaped within 60. And
When the next empty box is to be placed on this parts storage box 60, not only will each part P be pressed by the bottom of the upper parts storage box 60, but also the placement of the empty box itself. Is unstable, and accurate packing cannot be performed.

For this reason, as shown in FIG. 10A, in the parts box packing apparatus 100 of the second aspect, the guide gutter 33 of the guide gutter 30 is provided in a plurality of steps in the predetermined working space. Thus, the above-described problem is solved. Of course, the guide gutter 33 may be implemented by changing the vertical position of the predetermined work space to three or more steps, or may be implemented so as to move up slowly, that is, to move up slowly. Is also good.

In order to solve the above-mentioned problem, the means adopted by the invention according to claim 3 is that the parts box packing apparatus 100 according to claim 1 or 2 is described as follows. A separation bar 51 is provided which is vertically swung with respect to the side surface of the parts storage box 60.
Is pivoted downward to separate the parts storage box 60, which is supported at the bottom by its tip, from the one above it.

That is, in the parts boxing apparatus 100 according to the third aspect, each of the parts storage boxes 60, which are hardly detached due to deformation or the like, are forcibly separated by the separation bar 51. The box separating device 50 having 51 is provided on the holding frame 43 side of the empty box holding device 40.

As shown in FIGS. 5 to 9, the box separating device 50 includes a drive cylinder 52 operated by compressed air from an air supply source (not shown), and links rotatably connected to both ends of the drive cylinder 52. And a holding frame 43 on the side of the empty box holding device 40 integrated with the tip of the link 53.

In other words, in the parts boxing apparatus 100 according to the fourth aspect, as shown in FIG. 5, a space is formed in the machine casing 10 so that two rows of parts storage boxes 60 can be stored. According to this, the storage unit 11,
The support table 20, the guide gutter device 30, the empty box holding device 40, and the box separating device 50 as necessary are respectively enlarged. In addition, since a general parts manufacturing machine often has only one discharge port for the parts P, as shown in FIG. And a branch gutter 35 disposed between the guide gutter 33 and the gutter on the part manufacturing machine side.

The branch gutter 35 distributes the parts P flowing from one gutter on the parts manufacturing machine side to the respective guide gutters 33, and switches the flow direction of the parts P on the way. Are provided. For example, when the parts storage box 60 shown on the left side of FIG. 5 becomes full, the branch gutter 35 configured as described above switches the switching blade 36 to the opposite side by a signal from a detector (not shown) that detects this. That is, the introduction of the parts P into the parts storage box 60 on the right side of FIG. 5 is started.

Therefore, according to the parts packaging apparatus 100 according to the fourth aspect, the parts P can be packaged in a larger amount, and the compactness of the parts packaging apparatus 100 itself can be further reduced. You can do it.

The parts manufacturing machine for manufacturing the parts P discharges a large number of parts P at high speed as described above, but starts discharging defective products from a certain time due to various causes. Sometimes. In that case, the parts P already packed in the box must be removed, but when it is necessary to know from which part storage box 60 the defective product started, all the parts storage boxes 60 must be checked. In order to perform this check, it is necessary to drop down the parts storage boxes 60 that are full of parts P one by one, and this is generally a difficult operation.

However, in the parts boxing apparatus 100 according to any one of the above claims, basically, the latest parts storage box 60 in which the parts P are completely packed is piled up on the upper side. If the parts storage box 60 that does not contain defective items appears after removing the parts storage box 60 that is in order, it can be judged that there is a good product in the parts storage box 60 below it, and it is very easy to check You can do it.

In other words, the status check of the parts P in each of the parts storage boxes 60 packed and packed by the parts packing apparatus 100 according to the present invention is performed by sequentially performing the parts storage boxes 60 from the top. You can do it very easily.
